Jazz Emu’s rise in recent years has been monumental. In 2019, Archie Henderson’s comic creation was playing his keyboard alone in a room resembling a cupboard. Now he’s accompanied by a full band, selling out one of the more grandiose Pleasance spaces. One person in the long queue to get in even said that they now listen to his music non-ironically. That must be the stuff of dreams for a musical comedian.

The first thing to note about Knight Fever is that it’s purely silly. The narrative throughline is a simple one: Jazz Emu wants a knighthood, and only a blinding performance at the Royal Variety Show will secure it. However, this conceit is mere padding for a fairly unconnected selection of comic songs, even though it provides some of the hour’s funniest moments.

This unabashed goofiness is simultaneously refreshing respite from the surfeit of tragicomedy at the Fringe but can leave you wanting a little more substance. Some of Jazz Emu’s songs are categorically amusing, while others rely on the commendably tight musicians as a crutch. Turning a 419 scam email into a power ballad is funny, but it lacks a certain nuance that elevates other musical comedy acts such as Flight Of The Conchords to the next level. Also, the 70s lounge-funk stylings can feel slightly one-note eventually. In a way, Jazz Emu is good old-fashioned entertainment for a generation that know what Skibidi Toilet is. It seems unlikely that this is the zenith of Jazz Emu’s meteoric rise. After all, surely 264,000 TikTok followers can’t be wrong? Perhaps one day that coveted knighthood really will be his.
